Abstract (en)
[origin: WO2020128385A1] Disclosed is a method for filtering a fibrinogen composition, comprising the following steps: a) purifying the fibrinogen composition by chromatographic purification using an elution buffer comprising arginine; b) optionally, at least one step of filtering the fibrinogen composition obtained by chromatographic elution in step a), on a filter having a pore size of between 0.08 µm and 0.22 µm, c) filtering the fibrinogen composition obtained by chromatographic elution in step a), or optionally obtained in step b), on a symmetrical filter having a pore size of between 15 nm and 25 nm, and preferably between 18 nm and 22 nm, and d) recovering the resulting fibrinogen solution, the filtering method being carried out without adding arginine after step a), at a high capacity and without a prior freezing and/or thawing step.
